Procurement Notes
Verify the specific manufacturing origin and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the 2000-unit order increment aligns with production requirements. Ensure the automotive qualification level meets the target vehicle's specifications. Cross-reference the datasheet revision date to ensure compatibility with current design standards.
Selection Notes
Select this component when designing automotive circuits requiring compact common mode filtering for CAN bus lines. The 30 Ohm impedance provides adequate attenuation for standard automotive data rates. The low profile 2.0x1.2mm footprint is suitable for space-constrained automotive PCB layouts. Verify thermal performance under expected operating currents to ensure reliability within the specified temperature range.
Part Context
This part belongs to the AWCU series of common mode chokes from Pulse Electronics. It is functionally similar to other automotive-grade components like the AWCU00321619102M02 but differs in impedance and physical size. The series targets high-volume automotive electronics manufacturing, emphasizing reliability and consistent performance in harsh environments.
Replacement Considerations
The AWCU00201212300M02 may be substituted with other 30 Ohm automotive common mode chokes in the 2012 package if available. Verify pinout compatibility and impedance curves against the original design requirements. No direct public substitute part numbers are confirmed in the provided documentation.
